Kabbalah or Qabbalah. Teachings of Jewish mystics. The term encompasses all the esoteric teachings of Judaism which evolved from the time of the second
Temple. More particularly, it refers to those forms which evolved in the Middle Ages. Kabbalah draws on the awareness of the transcendence of God, and yet of his immanence (e.g., through
Sefirot). God can most closely be perceived through
contemplation and illumination. God both conceals and reveals himself. Through speculation and revelation, the hidden life of God and his relationship with his creation can be more nearly understood. Because mystical knowledge can so easily be misinterpreted its spread should be limited to those of a certain age and level of learning.
Although the influence of kabbalah was limited in the area of halakhah, the kabbalists created fresh
aggadic material and completely reinterpreted much early
midrashic aggadot. The classic anthology of kabbalistic aggadah is Reuben Hoeshke's
Yalkut Re'uveni (1660). Kabbalistic teaching and motifs entered the various
prayer books and thus spread to every
diaspora community. Popular customs were also affected by kabbalah, and kabbalistic ideas were absorbed as folk beliefs. These customs and beliefs were described by Jacob Zemah in
Shulḥan Arukh ha-Ari (1661). Popular ethics were also influenced by kabbalism, as is evidenced by such works as Elijah de Vidas'
Reshit Hokhmah (1579). From the 15th cent., attempts were made to harmonize kabbalistic ideas with Christian doctrines, and, although this tendency was derided by the Jewish kabbalists, it did serve to spread kabbalah beyond the Jewish community. K. von Rosenroth's version of kabbalah texts (
Kabbala Denudata, 1677–84) led the way to a popular appropriation of kabbalah outside Judaism, at least in
Theosophy.
